The Cryogenic Dark Matter Search (CDMS) employs Ge and Si detectors to search for weakly interacting massive particles (WIMPs) via their elastic-scattering interactions with nuclei while discriminating against interactions of background particles. CDMS data, accounting for the neutron background, give limits on the spin-independent WIMP-nucleon(More)
We report results from the Cryogenic Dark Matter Search at the Soudan Underground Laboratory (CDMS II) featuring the full complement of 30 detectors. A blind analysis of data taken between October 2006 and July 2007 sets an upper limit on the weakly interacting massive particle (WIMP) nucleon spin-independent cross section of 6.6x10;{-44} cm;{2}(More)
— Thick, fully depleted p-channel charge-coupled devices (CCDs) have been developed at the Lawrence Berkeley National Laboratory (LBNL). These CCDs have several advantages over conventional thin, n-channel CCDs, including enhanced quantum efficiency and reduced fringing at near-infrared wavelengths and improved radiation tolerance. Here we report results(More)
We report the first results from a search for weakly interacting massive particles (WIMPs) in the Cryogenic Dark Matter Search experiment at the Soudan Underground Laboratory. Four Ge and two Si detectors were operated for 52.6 live days, providing 19.4 kg d of Ge net exposure after cuts for recoil energies between 10 and 100 keV. A blind analysis was(More)
The CDMS experiment is searching for WIMP dark matter in our galaxy with novel cryogenic detectors that reject background photons. The experiment has begun first data taking in the summer and fall of 1996 (covering a period that extends beyond the date of this conference). We report on results from 60 g germanium and 100 g silicon detectors, including an(More)
Rats fed a zinc-adequate diet exhibited a nonuniform distribution of zinc in the small intestine. The zinc content of zinc-deficient rat small intestine was reduced, particularly in the duodenum and distal ileum. It is possible that the difference in the intestinal zinc content may reflect the rate of zinc absorption in the tissue. Uptake of 65-Zn by(More)
CDMS-II uses detectors known as Z-sensitive ionization phonons (ZIPs) to search for weakly interacting massive particles (WIMPs), a very promising candidate for the dark matter in the universe. The most recent data run utilized 12 ZIP detectors (six Ge and six Si) running for 1 2 year at the Soudan deep underground laboratory (780 m below surface),(More)
In the past year and a half, the Cryogenic Dark Matter Search (CDMS) collaboration has been active at the Soudan mine in installing a system for running ZIP detectors that will be used to search for dark matter in the form of Weakly Interacting Massive Particles. Presently, there is an operating cryogenic system, working electronics, a functional data(More)
The most recent CDMS data run (Run 20) was the first run in which multiple ZIP detectors were deployed. Three Si (0.100 kg each) and 3 Ge (0.250 kg each) ZIPs were run with the goals of fully testing such a configuration as well as measuring the γ , β , and n rates simultaneously with Ge and Si detectors. Calibration with γ and n sources established the(More)
